Schluter Kerdi: Shower Pan or Walls First?
When installing a Schluter Kerdi shower, the question of whether to install the shower pan or walls first often arises. While both approaches have their own merits, installing the shower pan first is generally recommended.
Here's why:
Benefits of Installing the Shower Pan First:
- More Accurate Leveling: Installing the shower pan first allows you to accurately level the pan itself, ensuring proper drainage. This also provides a solid, level base for the walls to be built upon.
- Easier Wall Installation: With the shower pan in place, you can easily attach the Kerdi membrane to the walls, ensuring a smooth and watertight transition from the pan to the walls.
- Prevents Damage: Installing the pan first prevents potential damage to the finished walls during pan installation.
Installing the Shower Pan First:
- Prepare the Subfloor: Ensure the subfloor is level, strong, and adequately supported.
- Install the Shower Pan: Follow the manufacturer's instructions for installing the Schluter Kerdi shower pan. Make sure the pan is properly leveled and sealed.
- Install the Kerdi Membrane: Apply the Kerdi membrane to the walls, ensuring a smooth and watertight transition from the pan to the walls.
- Build the Shower Walls: Construct the shower walls using your desired materials.
Considerations:
- Shower Pan Dimensions: Double-check the dimensions of the shower pan to ensure it fits perfectly with the planned shower walls.
- Plumbing Access: If you need access to plumbing behind the walls, ensure the shower pan installation allows for it.
Conclusion:
Installing the Schluter Kerdi shower pan first is generally the preferred method. It offers a more controlled and accurate installation process, ensuring proper leveling and watertightness. By following these guidelines, you can create a durable and leak-proof shower that will last for years.
